OBJECTIVE: In 2016 WHO classification, EBV +DLBCL of the elderly was replaced by EBV+ DLBCL NOS. This is due to the fact that many young patients of EBV+ DLBCL were found in recent years.
PATIENTS AND METHODS: In this study, we retrospectively analyzed clinical features and survival outcomes of EBV positive DLBCL patients in different age groups. All the patients treated at a single center.
RESULTS: When we use different ages (40, 50 and 60 years old) as cutoffs, the prevalence of EBV positive DLBCL was 12.0%, 12.3% and 13.0% in younger patients and 19.0%, 15.4% and 13.8% in elder patients respectively. Whatever the age cutoff was, EBV positive associated with unfavorable clinical prognosis in elder groups. When we use 40 and 50 years old as age cutoffs, poor impacts of EBV positive on overall survival and progression-free survival were observed only in elder patients, but not in younger patients. It should be noted that when we use 60 years old as age cutoff, the results were the opposite.
CONCLUSIONS: EBV+ DLBCL patients with age of 40 to 60 years old showed poorer prognostic features than EBV- DLBCL patients; however, patients in other age groups did not show evident differences in prognosis between EBV+ DLBCL patients and EBV- DLBCL patients. This finding was not reported before.Free PDF Download
